So here is what's happening from what I can see

you now don't get the best seats last

seats are allocated b c d e from middle of plane going backwards and forwards you are then left with mostly a and f seats from 6 to 29.

30 and 31 are left till last for weight and Balalce.

The rest are random from what I can see in the 50 or so tests I have made 16 and 17 are now not left till last and it seems the yellow seats also get allocate irregularly.

i believe it's now randomised or extremely complicated

i have not been able to get the seats I would have expected on any occasion so it's pot luck now I'm afraid.

i have been given 2 times 16 and 17 rows extral leg room when yellow and light blue seats were available.

if you want a seat where you want a seat pay for it no point in complaining ryan air have found out we never paid for a seat we wanted because there algorithm was so easy to predict.

as long as people post those things instead of keeping it a secret they will find out apologies for the bad and inevitable news. It was just a matter or time
